Useless app but good for advertising
Works really well
I used this app to clear my phone speakers of dust and it really worked. Not only is the sound quality better, but it is visibly cleaner as well. Since then I’ve dropped my phone in water, and I used this app again, and it worked amazingly!
Good free app
Helped me to get rid off water in charging port
